Ethylenically unsaturated monomers are polymerized in solution in an organic solvent in the presence of a Ziegler polymerization catalyst, by a process comprising (a) dissolving the monomer(s), including at least one gaseous monomer, in the solvent in a first absorption zone, the monomer having an exothermic heat of reaction when polymerized, the solvent increasing in temperature upon dissolving the monomer and decreasing in temperature upon vaporization of monomer therefrom, (b) introducing the solution into the polymerization zone, (c) introducing a polymerization catalyst into the zone, (d) polymerizing the monomers in the zone, (e) allowing a portion of the monomer to vaporize, thus removing at least part of the heat of reaction, (f) withdrawing the vaporized monomer, (g) admixing the withdrawn monomer with the solution obtained in (a) and prior to its entry into the polymerization zone, suitably in a second absorption zone, (h) cooling the monomer solution prior to its entry into the polymerization zone, and (i) withdrawing the polymerization solvent containing polymer from the polymerization zone. Optional process features include control of the molar ratios of the monomers used in copolymerization, suitably by means of a flow ratio controller or an analogue computer, cooling of the first absorption zone and of the polymerization zone, monomer recycling including purifying, and coagulation of the polymer solution withdrawn. A flow diagram of a suitable apparatus is given. Suitable monomers mentioned are monoolefins, conjugated and non-conjugated diolefins, bridged ring hydrocarbons, and vinyl aromatic hydrocarbons.

With valve 14 closed, as shown, gas, e.g. air or carbon dioxide, supplied to inlet 18 passes through Venturi inlet 20 to chamber 5 via passages 26, 28, and flexes membrane 4 to discharge liquid from chamber 6 via outlet check-valve 33, the valve 14 being held closed by the gas-pressure in passage 22. The differential pressure across the membrane is optionally partly or wholly compensated by a piston 16 subjected to the actuating gas-pressure and acting on rod 8. Towards the end of the discharge stroke, the tension of the membrane pulls rod 8 to open valve 14 thereby connecting gas passage 22 to exhaust port 25 via silencer 24. Gas from inlet 18 then flows through Venturi assembly 20, 21 to passage 22 creating suction in passages 26, 28, and chamber 5 to move membrane 4 on its intake stroke, valve 14 being held open by the airpressure in passages 11 and 22 acting on rod 8. Towards the end of the intake stroke membrane 4 moves rod 8 to close valve 14. The pump inlet and outlet check-valves 32, 33 each comprise a flap 34 connected by a hinge strip 35 to a sealing ring 36, the valve components being integrally moulded of flexible plastics.
